The Boyfriend is currently obsessed with remembering the name of an animated movie he saw in the theater in (he thinks) the 80's. All he can tell me is it is not set on Earth, has monsters, and has kids that have to fight/kill said monsters. But they don't want to kill the one they befriended, who is named Larry. (Not sure if it is a direct quote or not but he keeps saying "Don't kill Larry")
